7-Swollen lymph nodes
The lymphatic system is an alternate circulation of the blood where a fatty substance called lymph travels along with lymphocytes and other white blood cells. Lymph nodes are dispersed throughout the lymphatic systems, and it is a place of replication in many white blood cell lines. Thus, swelling of these lymph nodes is an important symptom, especially in the early phase of leukemia.
In most cases, swollen lymph nodes point out at an inflammatory or infectious condition in the surrounding tissue. However, there are certain locations and combinations of lymph nodes that may be suggestive of leukemia, and doctors are trained to detect these alterations and run the appropriate tests. Thus, if you don’t feel certain about your symptoms, talk to your doctor and follow his advice.
